Mount Everest is the highest point on earth with a height of 8,849 meters (29,032 feet). It is located between Nepal and Tibet, an autonomous region of China.

Mountain Everest is a symbol of relationship between Nepal and Tibet, and was named in the nineteenth century after George Everest, a former Surveyor General of India

A day on planet venus is longer than a year. This is so because it takes venus 243 'earth days' to spin round its axis (rotation), but takes 225 'earth days' to go around the sun (revolution).

In geography, understand that a day is reached when the planet makes a full spin or rotation round it's axis. However, a year is reached when a planet revolves fully around the sun

The Four Corners is a location in the United States of Ameria where one can stand in four states simultaneously (at the same time). The states are: Utah, Colorado, Arizona and New Mexico.

On the Four Corners, a person stands on the southwestern corner of Colorado, southeastern corner of Utah, northeastern corner of Arizona, and northwestern corner of New Mexico at once.

Pumice is a rock that floats on water

There are more stars in space than there are grains of sand on a beach

Earth's atmosphere is extremely important for the survival of all its inhabitants. As a student, it is important you comprehend how the above functions of the atmosphere support life. The explanations below give credence to this fact.

When one moves further away from earth, the atmosphere becomes thinner until it disappears into the outer space. There is no atmosphere in space. For this reason, astronauts will always wear a spacesuit while carrying along their oxygen gas masks and canisters when in space.

People living on very high altitudes will likely experience a reduced amount of oxygen in the atmosphere. Such people survive because their bodily organs become adapted to survive in such conditions.

On mountain everest for instance, mountain climbers will need to carry oxygen canisters because lesser amount of oxygen is present on this mountain.

The interface forming the boundary between two atmospheric layers are always named with a 'pause' at its end; for instance;

• Tropopause: This is the interface or boundary between the troposphere and stratosphere.

• Stratopause: Interface between the stratosphere and mesosphere.

• Mesopause: Interface between the mesosphere and ionosphere.

• Ionopause: Interface between the ionosphere and thermosphere.

The atmosphere surrounding the earth is layered. Each layer has its own characteristics although the boundaries between them are not clearly defined.

The image below shows the different layers of the atmosphere:

The average distance between the earth and the sun is about 149.6 million kilometers. It will take the earth 365 one-quarter days (or 1 year) to make a complete orbit (or revolve) round the sun. This process is termed the revolution of the earth.

The revolution of the earth is responsible for the seasonal changes we experience here (on earth). In Nigeria and Africa at large, these are the rainy and dry seasons. In Europe, these are spring, summer, autumn and winter seasons. Similarly, the United States of America have got the spring, summer, fall and winter seasons respectively.

The solar system is defined as a system comprising the sun, all the planets that revolve around it including their moons, the comets, meteoroids, asteroids and interplanetary medium.

In summary, the solar system comprises of the followings:

• Sun

• Stars

• Planets

• Moons or Satellites

• Comets

• Meteoroids

• Asteroids

• Interplanetary Medium (IPM)
